Select the option that best completes the analogy: Warm : Scorching :: Damp : ?

The relation is a mild degree : the extreme degree of the same quality. Scorching is warmth carried to its extreme, so damp must be paired with wetness carried to its extreme, which is 'Drenched'. 'Moist' and 'Humid' are the traps: both sit at the same mild level as damp rather than above it, so they fail the rise in intensity. 'Dry' is the opposite quality altogether.
